Explanation:

• Cardiac muscle cells are autorhythmic, meaning they can contract without instructions from the nervous system.
• Cardiac muscle has specialized cell junctions called intercalated discs which are important for coordinated contraction.
• Cardiac muscle cells have relatively short T tubules that do not form triads with the sarcoplasmic reticulum.
